Ulysses GAS UV Full-Sky Data
This Ulysses GAS experiment data set consists of pixel map data and image files for sky maps generated from GAS measurements in a mode primarily sensitive to ultraviolet photons. The accumulated counts and Ecliptic (spacecraft-centered) angle coordinates for each sky map pixel are given in the ascii files *.TXT. The positions of the Sun and the planets vary with time and with the position of the spacecraft along its trajectory, while the positions of stars remain fixed. The full images are provided in GIF (*.GIF files) and postscript (*.PS files) format, the GIF files being easily viewed on-line (see below) with an Internet web browser. The actual positions of Sun, Earth, and Jupiter are indicated by yellow, green, and white dots, respectively. The area around the Sun is excluded from observation to avoid damaging intensities from direct sunlight.\n\nThe files USER_GUIDE.TXT, FORMAT.TXT, and REFERENCE.TXT, respectively, give an overall description of the various datatypes, the record format for the DATA datatype, and a list of GAS-related publications. The users guide defines the nomenclature of the file names.
